Fuel Taxes
The California agency primarily responsible for fuel taxes is the California Department of Tax and Fee Administration (CDTFA). Interstate fuel users who operate a qualified motor vehicle in California and another state or a Canadian province are required to be licensed for fuel tax purposes.
Qualified Vehicle

(11,797 kilograms), or when used in combination, it has a combined registered gross vehicle weight exceeding 26,000 lbs.
Fuel Types
For fuel used on California highways, all fuel types other than gasoline must be accounted for.
Licenses
Commercial interstate fuel users in California must have one of the following licenses or permit:
- International Fuel Tax Agreement (IFTA) License
- Interstate User Diesel Fuel Tax (Interstate User) License
- California Fuel Trip Permit (CFTP)
